Our narrator has just arrived in the mysterious and remote base of some sort of evil organisation.
I’ve seen several “fortresses of evil” in my time. Mostly, they seem to fairly quickly attract the attention of the authorities, and they find out how little their power actually is in comparison to a sovereign state. This one, though, seemed fairly old; the white paint covering the walls was wearing through in places, and the metal floor beginning to rust. That was surprising, that this remote undersea base had somehow survived long enough to accumulate rust, when some evil leaders don’t manage to keep their building standing long enough for the first coat of paint to dry. Whoever it was running it, they knew what they were doing.
This was the sort of thing I lived to investigate. I have the power to turn invisible, and made my living, then, sneaking into this sort of base to report on what happened inside, but getting here had not been easy even for me. I had to stow away on a submarine bound for somewhere suspicious, keep hidden behind stacked boxes long enough to get some sleep on the journey, and then escape into this building, apparently an distribution centre for whatever illicit goods were being transported.
